KNOQKDOWN TABLE.

SPECIFICATION forming part of Letters Patent No. 273,109, dated February27, 1883,.

Application filed June 16, 1882.

To all whom it may concern:

Be it known that I, FRANK T. KNAUss, of Scranton, in thecounty ofLackawanna and State of Pennsylvania, have invented certain new anduseful Improvements in Knockdown Tables, of which the following is afull, clear, and exact description.

This invention relates to certain improvements in my knockdown tableshown and described in Letters Patent No. 257,343, .which were grantedto meMay 2, 1882; and itconsists principally in certain details ofconstruction of the frame, corner-plate, and means of attaching the leg,all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding partsin all the figures.

Figure 1 is a perspective view of the corner of a table-frame made inaccordance with my invention. Fig. 2 is a plan view of the same. Fig. 3is a detailed elevation of the upper end of the leg. Fig. 4. is anelevation showing the inside of the corner-plate. Fig. 5 is aperspective view of the back plate; and Figs. 6, 7, and 8 are detailedplan views,showing ditferent methods of uniting the ends of the rails.

A represents the corner-plate, which is so formed as' to be adapted tobe secured to the inside of the rails B B at the corners of the frame ofthe table, as shown in Figs. 1 and 2- This plate is preferably castconcave in form and with the flanges a a at its edges to fit in thegutters b 1), formed upon the inside of the rails, near their ends, withsuitable holes for the passage of the screws 0 c, for securing the plateto therails, and with the curbs d d upon the inside for staying theupper end of the leg 0 of the table, and with the central lug, 6, nearthe upper edges of the plate, as shown clearly in Figs. 1, 2, and 4. Theupper end of the leg 0 is preferably slotted, as shown at f, so that itmay be slipped upon the bolt F, and the said'lug e of the corner-platefits in this slot, as shown in Figs. 1 and 2, for bolding the leg firmand steady when in place, and for preventing the parts of the leg fromwarping or shrinking and closing tightly upon the bolt F, which wouldinterfere with the ready removal of the leg. The bolt F, which holds theleg in place against the inside of the corner-plate, may be madeintegral with the plate, or the corner-plate may be perforated in thecenter and a separate bolt used, if desired. This bolt is of sufficientlength to pass through (ModeL) the leg 0 and back plate, G, and toreceive the thumb-nut g upon its inner end for clamping all of the partsfirmly together. The not 9, when screwed up, comes against the plate Gas against a washer, and instead of using the back plate, G, an ordinarywasher might beused; but the back plate is preferred, and it ispreferably formed with the lug h on the inside, at or near its upperend, for entering the slotf of the leg, as shown in Figs. 1 and 2, forholding the plate in place and preventing the warping and shrinking ofthe parts of the leg.

ln expensive tables the joint between the ends of the rails will beformed with the extra corner-piece H, which will be held in place in anysuitable manner by dowel-pins, gluing, or otherwise, and some of thescrews for holding the corner-plate will pass into it, as shown in Fig.2; but in ordinary tables the joint between the rails may be an ordinarylap-joint, as shown in Fig. 6, or a miter-joint, as shown in Fig. 7, ora tongue-and-groove joint, as shown in Fig. 8. In most instances thebrace J will be used, which reaches from rail to rail outside of theupper end of the leg, as shown in Figs. 1 and 2. By this construction ofthe table it will be seen that the corner of the table-frame will bemade very strong, and that the legs of the table may be easily andquickly removed by simply loosening the thumb-nut g, to permit the legto slip out, and as easily and quickly replaced. Besides, the legs, whenin place, are held firmly, making the table very steady and strong.

The brace J may be omitted, if desired, as the corner is made verystrong without any bracing by the corner-plate A.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. The combination of the rails 13, having gutters b b,the slotted leg 0, the clampingbolt F, back plate, G, not 9,corner-piece H, and the concave cornerplate A, the latter arranged uponthe inside of rails, and provided with' the flanges a, curbs d, andcentral lug, e, as shown and described.

. 2. The rails B B, formed with the gutters b b, in combination with thecorner-plate A, formed with the flanges a a, the extra cornerpiece H,leg 0, bolt F, and brace J, substantially as described.
